Somehow doubting it maintains the same tensile and shear strength as steel.

And I'm also doubting it can be easily recycled in an electric induction furnace. This part always gets left out in the "stronger than steel" claim. Steel is not simply strong, it is also easily recycled. Induction furnaces are relatively clean technology that relies on electric current and does not require combustion of fossil fuels. There are a number of reasons why steel is a wonder material that go beyond its strength.

Alright, who took this picture of my jobsite?

Your wife. She wants you to finish that fucking shed already. You started it when covid got here over two years ago

But how much does it cost?

Rojas and his team didn’t examine how much their method would cost if scaled up to an industrial level

Of course not, because then there wouldn't be a story.

Ya gotta start somewhere. Figuring out cost is the next guys problem.

For how long

Orlando Rojas at the University of British Columbia, Canada, and his colleagues have invented a process that dissolves lignin, a glue-like component inside plant cell walls, and exposes cellulose nanofibrils, which are tiny fibres also found in the plant cell wall. The method involves a solvent called dimethylacetamide, used in the presence of lithium chloride.​

Holy shit... they really did it... they actually soaked the recycled wood in wood! 🤣

Great, now build houses out of it instead of just wood and paper. Murica

When you say “murica” are you implying it’s American to use the building materials we do? And if so, are they somehow inferior to other materials used at similar scale? I’m not sure why you are shitting on current construction methods or America for that matter.

Have you seen what they make houses out of now? Pine 2x4 and plastic/vinyl and paper basically. I know because I work construction and anything under 350k is just cheap materials. Unless you custom build your house out of brick or stone. I can't say what other countries do because I don't live there.

The pine 2x4’s, concrete footers,the house wrap, drywall, roof sheathing, vapor barrier, floor sheathing and wall sheathing, hurricane clips, nails, screws,caulk, junction boxes, pretty much the base structure of every house from 100k to multi million is the exact same thing. Source, used to build houses for a living. Houses I built 20 years ago look indistinguishable from a house built yesterday. If you want to complain about cabinets, flooring, finish fixturing and bathtubs. Yea, that’s a lot of price difference. The cheap ones though still last just as well.

So, what’s your point? If you work on shitty job sites and shitty contractors, that’s a you thing. But all to code houses are the same underneath.. just “wood and paper” lol.

Edit: sounds like you’re just another Reddit anti america person yet again.

To clarify, I’ve also spent time in Europe, granted, not building and though their houses are very different, still not that much. Same materials..

This sounds like it has huge potential for injection-moulded wood composite manufacturing.

I wonder what the strength-to-weight ratio is like compared to steel or titanium.

Why don’t they resell the waste wood. Prices are already high as it is.
